Gadzirisa vJunos-chinja paKVM

SUMMARY
Verenga iyi musoro kuti unzwisise maitiro ekugadzirisa iyo vJunos-chinja munzvimbo yeKVM.

MUCHIKAMU INO
Batanidza kune vJunos-chinja | 19 Gadzirisa Active Ports | 20 Interface Naming | 20 Gadzirisa iyo Media MTU | 21

Batanidza kune vJunos-chinja
Telnet kune serial console nhamba inotsanangurwa muXML file kubatanidza kune vJunos-chinja. Ona zvakadzama zvakapihwa mu “Deploy and Manage vJunos-switch on KVM” papeji 11. For ex.ample:
# telnet localhost 8610

Kuedza 127.0.0.1… Yakabatanidzwa kune localhost. Escape character is '^]'. mudzi @:~ # cli mudzi>
Iwe unogona zvakare SSH kune vJunos-chinja VCP.
Gadzirisa Active Ports
Ichi chikamu chinotsanangura maitiro ekugadzirisa nhamba yeanoshanda ports.
Iwe unogona kutsanangura huwandu hwezviteshi zvinoshanda zvevJunos-chinja kuti ifanane nenhamba yeNICs yakawedzerwa kuVFP VM. Nhamba yekusarudzika yezviteshi igumi, asi unogona kudoma chero kukosha muchikamu che10 kusvika 1. Mhanya mushandisi@host# set chassis fpc 96 pic 0 nhamba-yezviteshi 0 raira kuti utaure nhamba yezviteshi zvinoshanda. Gadzirisa nhamba yezviteshi pa [edit chassis fpc 96 pic 0] nhanho yehumambo.
Interface Naming
Iyo vJunos-switch inotsigira chete Gigabit Ethernet (ge) nzvimbo.
Iwe haugone kushandura mazita ekubatanidza ku10-Gigabit Ethernet (xe) kana 100-Gigabit Ethernet (et). Kana iwe ukayedza kushandura mazita ekushandisa, ipapo aya mainterface acharamba achiratidza se "ge" kana iwe uchimhanyisa dhizaini yekumisikidza kana kuratidza interfaces terse mirairo. Heino example kubuda kwe "show configuration" CLI command kana vashandisi vachiedza kushandura zita rekushandisa kuti "et":
chassis {fpc 0 {pic 0 {## ## Yambiro: chirevo chakafuratirwa: chikuva chisina kutsigirwa (ex9214) ## interface-type et; }

21
}}
Gadzirisa iyo Media MTU
Iwe unogona kugadzirisa iyo media maximum transmission unit (MTU) muhuwandu hwe256 kuburikidza ne9192. MTU tsika kunze kweiyo yakataurwa pamusoro apa inorambwa. Iwe unofanirwa kugadzirisa iyo MTU nekubatanidza iyo MTU chirevo pa [edit interface-zita] hierarchy level. Gadzirisa iyo MTU.
[edit] mushandisi@host# set interface ge-0/0/0 mtu
CHERECHEDZA: Iyo yepamusoro inotsigirwa MTU kukosha ndeye 9192 bytes.
For example:
[edit] mushandisi@host# set interface ge-0/0/0 mtu 9192
